To all Aw/iom. t may concern.'

lie it known that l, PAUL A. Mnmmr, citizen ot' the United States, andresident ot' New Castle. in the county of Lawrence and State mPennsylvania, have invented certain new and useful improvements inKiln-Cars with Adjustable york-Supports, of which the following is aspecitcation.

The general object of my present invention is to provide nnproved meansfor transporting goods through continuous tunnel kilns. Morespecifically the object of my invention is to provide xgoodstransporting means for the purpose specified with simple and effect ivemeans for moving the goods on the goods transporting means as the latterymoves through the kiln.` so as to equaliae the heat absorption b vdifferent portions of the goods.

The invention was primarily devised for use in vulcanizingr tires butcan adv-.inta geously be used in the treatment of many kinds oi goods.

The various Jfeatures of novelty which characterize nl v invention arepointed out with paricularity in the claims annexed to and forming a`part ot'. this specification. For a better understanding of theinvention. however, and the advantages possessed by it reference shouldbe had to the accompanyY ing drawings and descriptive matter in which Ihave illustrated and described preferred forms of apparatus embodying myinvention.

Of the drawings:

Figure 1 is an elevation of a portion of a tunnel kiln with one forni ofmy improved goods transporting;r device therein.

Fig. 2 is a transverse section on 2--2 of Fig. 1.

Fig. 3 is a plan view of a modiied form of goods transporting device;and

Fig. fl is a section on the line f--fl of Fig. 3.

ln Figs. 1 and 2 ol the drawings, I have illustrated the use oi' myinvention in connection with continuous vulcanizing apparatus comprisinga tunnel kiln llwith track rails S `for the ears' A which carry thearticles to be vulcanized through the kiln, and havin; combustionchambers T For heating' thr kiln located at the sides oi the pathway forthe goods The kiln illustrated is of tile weil known Dressler type asshown. iur ea: cple.

` tire molds supporting it may be Patented Mar. l5, 1921i 1920. sum1 No.375mm by the patents of Conrad Dressler 1U23l325 and 11704-28, but it tobe understood that the invention is not limited to use in any particulartype of tunnel kiln.

The goods carrying car l shown in Figs. l and comprises` a body portionA, Wheels B, and axles ille latter being mounted in bearings carried bythorar body. The car body A is provided at its opposite sides withuprising standards or brackets: Az in the upper ends of which arejournaled a` shaft D. The latter carries spiders on which aredetaclial'ily mounted the articles to transported tl'irongh the kiln. Asshown these articles consist of the heavy metallic molds lj in whichvehicle tires ai vulcanized. Provisions are made for rotating the shaftD, and thereby the tire molds and in chased` tires, as the car Amovesalong the track rails Si. The provisions shown for this puriiiose.conilnise .1 pair of roller supports l joui-nailed, one on each ot' theor-.ickrts A?. and 'forming swliports for rollers D secured to the endsol' the shaft l). The latter has its und portions received betweenbil'ureations Ap in which the upper end ofeaeli bracket A terminates.Secured to the shaft 'for earl) roll l? is a sprocket gearG. Each rearil is eoniiected by a sprocket chain ll to a corresponding sprocket gearC1 carried by one of the rar axles (l.

vWith the described construction as the ear A moves through the kiln.the supporting wheels F tor the shaft D. and thereby the latter. arecorrespond'ugly rotated. The rotation ol' ille shaft D revolves the riremoldsl P carried by the shaft. This tends to equalize llie heat:fibsorption by the nods l when, as only sometimes happen, thetcmperature in the upper portion of the kiln chamber is higher 1than thetemperature in the lower portion l. The shaft D with the lifted bodilyoff the brackets when the removal of the molds is desired.

it will be understood of course that many different arrangements magT bemade for automatically rotating, or otherwise moving goods carried on akiln car, relatively to the latter as the rar is moved through the kiln.For iin-larice. il nia); be desirable to roi-ate the `rood ab' nl. avertical axis instead of a horizon ir cases where the character of theruin i infix, that zlilelenoes in temv -axles C so that as th articlesto be 4 Eerature may exist between the sides of the iln chamber and thecenter of the latter.

ne form of apparatus for accomplishing this is shown in Figs. 3 and 4.The kiln qirs shown in Figs. 3 and 4 comprise a car y AA and a goodscarrying revolve about a vertical s shown the goods cari' ing member Irests upon balls or rollers JY held in an annular runway A formed on thecar bod AA The member I has a dependin shaftI carrying pulley wheelsgIt. A cable belt HA connects the pulley wheels I3 with pulley wheelsU10 secured to the car c ear is moved along its supportinv track railsthe goods su porting member is rotated. As shown t ody is formed with arefractory superstructure A", and the goods carrying member I comprisesa refractory upper portion Il of cylindrical form received in acylindrical opening formed in the refractory car portion A1. he goodsmay be mounted directl on the upper end of the revolvin tion ,-but asshown, a stand member A is seated -on the portion Il.y and is providedwith spiders EA on which tire molds simil lai' to those shown in Figs. 1and 2 or other treated in the kiln may be mounted.

With the construction shown in Figs. 3 and 4 the roller bearing for thegoods supporting member and the gearing connecting the latter to the caraxle are protected against lthe .high temperature in the upper portionof the kiln chamber by the re rachory ciuportions A10 and I1 so thatthis form of my invention is adapted for use with relatively high kilntemperatures, such a tunnel kiln com as are employed for example inmetal anhealing su bstantially higher than those comly employed invulcaniziiig.

and demy invention now claim as new, and desire to secure by LettersPatent, is:

1. The combination with a tunnel kiln of a cai' for moving goods throughthe kiln and goods supporting means mounted on said car and adapted tomove the goods relative to] the rar as the latter is moved through the2. A car for transporting goods through rising in combination a carbody, a rotatab e goods su porting memand means he car moves. for movintunnel kiln comprising in combination a car body, supporting wheelstherefor, and a' revoluble goods supporting member j naled on the carbody and geared to the car wheels to rotate with the latter.
